JOHN H. SIMPSON, OF PROVIDENCE, RHODE ISLAND.

EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 731,963, dated June 23, 1903.

Application filed November 17, 1902. Serial No. 131,695. (No model.)

To all whmn it may concern:

Be it known that I, JOHN H. SIMPSON, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Extinguishers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to extinguishers designed to be connected to the wick-tube of an illuminating or heating burner, and when the wick is turned down to automatically extinguish the flame.

The object of the invention is to provide a device of this character which may be built up in the construction of the burner or which may be made and sold to the trade as a separate article of manufacture and be applied to the burners now in general use.

A further object of the invention is to provide a device of this character by means of which the extinguisher-plate may be easily, quickly, and securely attached to the body of the device.

WVith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure l is a front view of a burner with the dome swung back and illustrating my improved extinguisher attached to the wick-tube. Fig. 2 is a detail perspective view of the extinguisher removed. Fig. 3 is a similarview of the parts constituting the extinguisher, showing one of the lugs in the position it must assume in order to connect the extinguisher-plate with the body of the extinguisher. Fig. 4 is a 1011- gitudinal vertical sectional view through the extinguisher with the extinguishenplate elevated. Fig. 5 is a similar view with the extinguisher-plate lowered. Fig. 0 is a detail perspective View of a wick-tube constructed with my improved extinguisher.

Referring to the drawings, 1 denotes a frame, which may be represented by the upper end of the wick-tube, as shown in Fig. 6, or

which may be represented by a removable clasp, as shown in the remaining figures. hen it is of the form shown in Fig. 6, it is understood that the extinguisher is adapted to be built up with the burner in its course of manufacture and when it is of the form shown in the remaining figures it is understood that the frame is adapted to be secured to the wick-tubes or burners now in general use. In either case that part of the extinguisher which I have preferred to call a frame is provided with a horizontal flange 2, terminating in an upwardly-projecting support 3, said flange and support attheir junction being formed with a longitudinal slot 4, which is intersected at one end by a vertical slot 5.

6 denotes the extinguisher-plate, which is provided with two arms, the combined length of which and the rear edge of the plate of which they are a part being greater than the length of the longitudinal slot. Previous to the connection of the extinguisher-plate with the frame one of the arms is preferably bent forwardly, so that the other arm may be in sorted through the slot and engaged with the rear face of the end wall thereof, after which the bent arm is inserted through the vertical slot. This having been done, the bent arm is then straightened, thus securely connecting the extinguisher-plate with the frame.

In operation as the lighted wick is turned down the extinguisher-plate will follow it, and thus extinguish the flame. WVhen it is desired to light the lamp, the wick is turned up in the usual manner, the extinguisherplate swinging upon its joint out of the way to freely permit the upper end of the wick to be raised to the desired height. The extinguisher-plate being in close proximity to the flame becomes heated to a high degree of temperature, and thus transmits a part of its heat to the oil drawn up by capillary action through the wick, and thus tends to promote a high degree of combustion.

From the foregoing description, taken in connection with the accompanying drawings,

the construction and operationof theinven tion will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion,

and the minor details of construction may be frame, the arm is adapted to be bent at right angles to the plane of the extinguisher-plate, and after the extinguisher-plate has been at tached, the arm is adapted to be bent straight and thus lock the extinguisher-plate with hinge connection tothe frame, substantially as shown and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
